2 Claims. (Cl. 297--421) This invention relates to an arm chair, and more particularly to the construction and mounting of the armrests on the chair arms. This application is a division of my application Serial No. 732,995, filed May 5, 1958, now Patent No. 2,942,654, issued June 28, 1960.

It is an object of my invention to provide a chair of the type referred to which can be simply and economically manufactured, which will be of attractive appearance, which will prove sturdy and durable in use, and which can be readily assembled, thus lending itself to shipment and storage in a knocked-down condition.

In carrying out my invention in its preferred form, I provide a seat mounted on a suitable licor-engaging base and connected to a chair back mounted above the plane of the seat at the rear edge thereof on suitable supports. A pair of side arms conveniently formed from lengths of metal-tubing are connected at each of their ends to the chair seat and back to brace the back on the seat and enhance the comfort of the user. The upper stretches of the arms are provided with elongated padded armrests rigidly mounted along the upper faces of the upper stretches of said arms.

Other objects and features of the invention will become apparent from the following more detailed description and from the accompanying drawing in which:

FIG. l is a front elevation of a chair embodying my invention;

FIG. 2 is a side elevation of the chair shown in FIG. 1;

FIG. 3 is an enlarged horizontal section showing a method of mounting the chair arms to the back rest; and

FIG. 4 is a vertical section taken on the line 4-4 of FIG. 2.

My invention is shown in the drawing as being embodied in an oilice side chair merely for the purposes of illustration, since my invention contemplates the provision of a chair, settee, or the like provided with a pair of side arms having elongated padded armrests mounted on their upper horizontal stretches. In the chair illustrated, there is provided a seat 1i) mounted on a doorengaging base, comprising pairs of front and rear legs 26 and 1S respectively. A back 29 having a padded covering overlying a mating back-pan 30 and back-panel 31 is mounted above the plane of the seat and at the rear thereof upon vertically extending back supports 32 connected to said back-pan and panel and to the rear edge of the seat It). The structure of the seat and back, together with the door-engaging base, forms no part of the invention of the present application, for it constitutes features of the parent application Serial No. 732,995, filed May 5, i958, from which this application was divided.

As illustrated in the drawing, the chair is provided with a pair of side arms 40 secured to the lateral edges of the seat jill and to the back 29 at its connection to the supports 32 to enhance the comfort of a person using the chair and to brace and stabilize the back 29. Each arm 40 comprises a length of metal-tubing being generally square in cross-section and bent into a generally L-shape with its extreme lower portion deformed so that its end face abuts the lateral face of the seat 10 for connection thereto. The opposite or upper ends of the arms 40 extend through openings in the lateral stretches of the back-pan 30 and hack-panel 31 and are interconnected to the chair back 29 by securing said arms to the supports 32. In this manner, both the supports and back are stabilized and braced against movement with respect to the chair seat 1t). In providing such an arm-to-back mounting the ends of the arms are attened and bent into channel sections 47 which partially circumscribe the back supports 32 and bindingly retain them therein. As shown in FIG. 3, the webs of the channels 47 are pierced for the reception of bolts 35 so that the arms 40 and the back supports 32 may be secured to the back-pan 30 by the same bolts. Conveniently, the material around the bolt receiving openings in the outer faces in the arm and the back support is deflected inwardly, as at 48, to form a frustoconical seat so that the bolt may be countersunk in the arm 46.

As illustrated in the drawing, the subject matter of the present application is characterized by the provision of armrests 52 rigidly mounted on the upper faces of the horizontal stretches of the arms 40. Each ofthe armrests 52 comprises an elongated bracket 54 having a web 58 embracing the upper face of an arm 40 and an upstanding peripheral flange 56. A second bracket 6i) having a web 64 and a downwardly extending peripheral ange 62 is mounted above the bracket 54 with the ange 62 of the bracket 69 disposed adjacent the outer face of the flange 56. The ltwo brackets are mounted on the arm 4i) as by bolts 65 passing through openings in the upper and lower faces of the arm 40 and through openings cut in the web 53 of the bracket 54, the upper ends of said bolts being received in nuts 66 lixedly retained in the web 64 of the bracket 60. A layer of padding 68, desirably formed from a resilient material such as foam rubber or the like, is placed over the upper face of the bracket 6G, and is covered with a llexible skin 70 with the margins of said padding and skin being bindingly retained between the peripherally extending flanges 56 and 62.

Assembly of each of the armrests may be described as follows: The padding and skin are disposed over the upper face of the bracket 60 with their margins wrapped around the end of the flange 62. The bracket 60, with the padding and skin thereon, is then press-tit over the bracket 54 with the iianges 56 and 62 bindingly gripping the padding and skin. -The armrest is then placed on the upper face of the arm 40 and the bolts 65 are drawn up into the nuts 66 to xedly secure the armrest on said arm.

I claim as my invention:

l. In combination with a chair having a seat mounted on a door-engaging base and provided with a pair of side arms interconnecting said seat to a back at the rear of said seat; an arm rest mounted on the upper face of each of said arms, each of said arm rests comprising a lower bracket havinfy a central web carrie-d against the upper face of a chair arm and provided with an upstanding peripheral flange, an upper bracket having a downwardly dished central web provided with a peripheral ange extending downwardly over the flange of said lower bracket, a pad on said upper bracket, a skin covering the pad forming the upwardly presented arm rest face, the marginal edges of said skin extending around the liange on the upper bracket and disposed in frictional engagement with the adjacent faces of the flanges on said upper and lower brackets whereby movement of the upper bracket into its assembled position with its flange extending over the flange on the lower bracket will pull said skin and pad over the upwardly presented arm rest brackets and retain said pad in a fixed position thereover, and means interconnecting said brackets and holdnig said upper bracket in said assembled position.

2. The combination as set forth in claim 1 in which said means extends through said lower bracket and chair arm, and comprises a pair of cooperative fastening members including a rst member disposed in a iixed position in the web of said upper bracket, and a second member threadabiy connected to said first member Whereby said first and second members rigidly retain the arm rest on the chair arm and retain said brackets in assembled position.
